OVA
Description
Isamu, known professionally as Child Emperor, is a ten-year-old professional hero and the youngest member of the Hero Association. He holds the S-Class Rank 5 position, a status earned through his extraordinary intellect and strategic prowess rather than physical strength. His sharp mind allows him to outmaneuver most heroes and formulate effective combat plans, often placing him in a leadership role during S-Class missions—though some veteran heroes remain reluctant to follow a child’s commands.
His original Japanese hero name, Dōtei, carried an unintended double meaning as “male virgin,” which became a source of embarrassment and led to teasing by peers. This prompted him to change his name to “Wild Emperor”—or “Diabolical Emperor” in certain localizations—upon joining the rival Neo Heroes. The new alias, Hidōtei, sounds similar to the Japanese term for “non-virgin.”
His capabilities are largely technology-based. A genius inventor, he works from a personal laboratory where he designs advanced gadgets, most of which are stored in a standard-looking school backpack equipped with compression technology. This bag holds an extensive arsenal, including extendable robotic legs for mobility and numerous other devices.
His most powerful invention is the Brave Giant, a massive and customizable mecha suit. Originally deemed too generic, it was later redesigned to be more unique. The mecha is stored in parts throughout the city and can be summoned to assemble on demand.
Outside hero work, Isamu lives a double life as an elementary school student. He attends classes like any other child but, due to his superior intellect, teaches afternoon lessons to his peers. Despite his occasional arrogance among heroes, he is well-liked at school.
In combat, he relies on technology, strategy, and physical enhancements from his inventions rather than raw power. He has proven durable, capable of enduring heavy attacks and continuing to fight.
After the Monster Association arc, Child Emperor becomes one of the first prominent heroes to leave the Hero Association for the Neo Heroes. His move is part of the Neo Heroes’ ascent and their concealed darker agenda. In this new organization, he works alongside other defectors such as Metal Bat and Superalloy Darkshine, who sometimes have difficulty adjusting to his rebranded identity.
